Vox Guitar amp part identification problem

08-18-2010, 10:30 PM

I am trying to identify an operational amplifier number. It reads these characters on three lines:

Top: 0720
Center: JRC
Bottom: 9012B

No attempt I've made to get any combination of these characters has managed to bring up any data.

The op-amp (2 each) are part of a Vox Valvetronix guitar amplifier (VT-15) that the Vox People won't give me a schematic or parts info for. Can any one help me id this component or cross it???

Yep, they are plain old common TL072.

Amazing!! Who would ever have guessed that someone who villified the evil rich people would begin happily accepting their millions in speaking fees!

Oh, wait! That sounds familiar, somehow.
